CommentThis HMM describes nitrogenase (EC iron protein, also called nitrogenase reductase or nitrogenase component II. This model includes molybdenum-iron nitrogenase reductase (nifH), vanadium-iron nitrogenase reductase (vnfH), and iron-iron nitrogenase reductase (anfH). The model excludes the homologous protein from the light-independent protochlorophyllide reductase.
